Evaluation of methods and results of dredging waste and dump sampling at ore deposit

Abstract

The purpose of the study is to assess the reliability of sampling results of concentration tailings at the experimental site of Tereklikan of Kanjol deposit (Tajikistan). The study involves the description of dredging waste and dumps of the site under investigation. The total length of the sampled interval is 12 m. It was divided into two local intervals of 4 and 6 m long according to geological features (amount of veined quartz material). Each type and component of the sampling process including the study of the mineral and chemical composition of ores is of utmost importance in the determination of the quality and quantity of the ore mass (ore), whereas the study of ore mineral and chemical composition is used during prospecting and exploration works for ore minerals (lead, zinc, tin, gold, copper, aluminum, manganese, etc.). The authors substantiate the feasibility for technogenic deposits formed under non-ferrous metals mining to be involved in operation. The methodology and channel sampling results are presented and the reliability of the latter is assessed. The methodology and results of physico-chemical research of concentration tailings via spectral analysis and atomic absorption method are given. The industrial significance of ancient dredging waste and dumps as well as the content of valuable components sufficient for their development has been established. An acceptable technology of dredging waste and dumps processing when involved into operation has been proposed.
